Generic Function Create-Scanner (3 methods)

( create-scanner < regex > &key < case-insensitive-mode > < multi-line-mode > < single-line-mode > < extended-mode > < destructive > )

Accepts a regular expression - either as a
parse-tree or as a string - and returns a scan closure which will scan
strings for this regular expression. The “mode” keyboard arguments
are equivalent to the imsx modifiers in Perl. If DESTRUCTIVE is not
NIL the function is allowed to destructively modify its first argument
(but only if it's a parse tree).
